BLOCK AND TYING MECHANISM FOR BALINGr-PRESSES.

Patented June 4, 1918.

Original application filed December 11, 1916, Serial 1\To..136,143. Divided and. this application filed August To all whom it may concern:

Be it known that I, UBERTO D. EZELL, a citizen of the United States, residing at Kimball, in the county of Bosque and State of Texas, have invented certain new and useful Improvements in Block and Tying Mechanism for Baling-Presses, of which the following is a specification.

This invention relates to improvements in blocks and tying mechanism for baling presses and is a divisional application covering means originally disclosed in my apfor baling press filed December 11th, 1916, and bearing Serial Number 136,143 which eventuated in patent No. 1,237,495, August 21st, 1917.

The main features of the invention are a hollow block, a plurality of which may be used in a press, and a tying mechanism including transversely operating needles or plungers entering the blocks and cooperating with means therein for tying the bale wires.

The invention will be more readily understood from a perusal of the following specification and by reference to the accompanying drawing, in which an example of the invention is shown, and wherein:

Figure 1 is a detail of the tying plungers,

Fig. 2 is a side elevation of the same parts,

Fig. 3 is a partial plan of the press equipped. with the invention, portions being broken away Fig. 4 is an enlarged longitudinal sectional view of the parts shown in Fig. 3,

Fig. 5 is a side elevation of the parts shown in Fig. 3, I

Fig. 6 is a sectional detail showing a portion of the press and the block,

Fig. 7 is a transverse vertical sectional view of the block and press, and

8 is a detail of the wire twisting head.

In the drawings the numeral 1 designates the bottom of the baling chamber of a press, which is also provided with side walls 2 and atop 3. The press comprises aplunger (not shown) and other necessary parts. for instance as shown in former application. An endless connection comprising two endless belts 17 passing over rollers 18, is provided in the baling chamber, the return run of the belts passing under the bottom 1, these belts having sliding engagement with hollow baling blocks 20; while coiled to illustrate underlying parts,

springs 19 attached to each side of the blocks have their outer ends secured to the belts. In this way the blocks are resiliently held on the belts and may slide relatively there of when subjected to heavy pressure.

As the baling advances the blocks are car ried outward toward the end of the press. The blocks as before stated are hollow and each comprises a central web 40 which unites the parts. Each block is virtually separated into three sections by slots 41 and 42. At each side of the press needle or plunger guides 43 are mounted and carry transversely operating needles or plungers 44. and 45 respectively, there being two needles 44 in superposed order on one side, and two needles 45 in opposed relation thereto on the other side. Each needle has gear teeth along one edge engaged by a pinion 46 fixed on a shaft 47 which in turn is revolved by a pinion 48. As the operation of the upper set of needles is the same as the lower set, a description of one will do for both.

The baling wire 49 from a spool 50 on the wall 2 is led through the eye of the needle 44 and looped across the baling chamber to the clamp 51 on the end of the needle 45. As the hay is pressed against the wire the same is drawn through the eye so that it surrounds the bale on three sides, the

block being against the other side. Within the baling chamber is mounted a pair of gear racks 52, one on the bottom 1 and the other on the under side of the top 3. The rack 52 is positioned so as to be engaged by a pinion 53 counter-sunk in the top of the block, when said block arrives between the needles. The block also has gear racks on each side, traveling in grooves in the sides 2, and being engaged by gears 61 mounted in mesh with the pinions 48 and extending through the sidesof the chamber.

As the block advances the shafts 47 are revolved whereby the needles are driven into the blocks through the slots 41 and the wire carried through the slots 42. The pinion 53 is fixed on the upper end of a vertical shaft 54 mounted in a bracket 55 within the block and on one side of the web 40. A bevel gear 56 on the lower end of the shaft meshes with a bevel gear 57 which is attached to a wire twister 58 mounted on the opposite side of the web and having a neck 59 behind its arms. As the needles approach each other the twister is revolved and the wires are twisted together at the apex of the twister and around the neck 59, the twist around the neck being unwound to releasethe twister.

The block is fina-llymoved to such a position that a boss 63 on the wall of the press is .engaged by a spring pressed plunger 64: mounted in the block and attached to the ledger'blade of a pair of shears 65. When the plunger is depressed the shears'are op- ,erated and the wire cut. In the mean time the needles have advanced to an overlap- .ping point and the clamp 51 has been opened by engagement with a pin 66 on the web 40. One end of the twisted wire isv released by the clamp and the Other end is cut of? by the shears, thus leaving the endof the untwisted-wire in the clamp. When the needles are driven into the block they extend coiled .springs'67 which act to return the needles to their normal position when the racks 60 ride out of mesh with the gears 61. When the bale is pushed out of the baling chamber from around the neck 59 and the operation willvbe complete.

What I, claim, is: v 1. In a device of the character described, the. combination with the baling chamber of a press, of a hollow block movable longitudinally of the chamber,. Wire twisting mechanism mounted in the block, and reciprocating membersmounted. on the chamber to traverse the block transversely ,and arranged for carrying baling wire to the twisting means of the blocks. r

I 2; vIn a device of the character described, the combination with the baling' chamber of a press, :of a hollow block movable longitudinally of the chamber, a wire twisting de- Vice mounted in the block, a wire cutting dev cealso mounted in the block, and reciprocatmg wire carrying members mounted on the chamber to enter the block and cooperate with the twisting and cutting devices.

3. In a device of the character described,

ber of a press, of transversely reciprocating needles mounted on the chamber, gears for driving the needles into the chamber, means for retracting the needles, a hollow block traveling longitudinallyof the chamber and having gear racks engaging the driving gears for operating the same, 'and a wire twisting device mounted in the'block, said needles entering the block.

it will pull the twistedends of the wires 5. 'The combination with the baling chamber of a press, of transversely reciprocating needles mounted on" the chamber, gears for driving the needles into the chamber, means for retracting the needles, a hollow block traveling longitudinally of the chamber and -having gear racks engaging the driving gears carried by the block for operating the same, a wire twisting device mounted in the block, means for operating the twisting device carried by the block, and an operating device mounted on the chamber and engaged by said last named means for latter.
